spaceships have been abandoned, only the nose cone
being used to bring the crews back to earth. 【S4】______
Upon established, each space station will generate 【S5】______

need to rotation to provide an artificial gravity; people 【S6】______
will be forced inwards from the centre by centrifugal 【S7】______
